Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To obtain a material having affinity for super antigen even in a solution having high protein concentration in a neutral region, capable of sterilizing and containing inexpensive urea bond or thiourea. SOLUTION: An urea or thiourea compound containing a group capable of forming hydrogen bond with an aromatic ring and represented by the formula (X is O or S; K is a number of >=0; R1 , R2 and R3 are each a group capable of forming H bond or an aromatic substituent group) is suitable as a material for removing or deoxifying a super antigen, especially as a body fluid purifying column for removing the super antigen and a wound coating material having absorbing property to super antigen. The super antigen is removed from a liquid by passing the liquid (e.g. blood, plasma or serum) containing the super antigen such as exotoxin of Staphylococcus aureus or exotoxin of Streptococcus through a column in which the material is packed. The material can be used for diagnose, prevention and treatment of food poisoning, sepsis and autoimmune diseases.

IPC: F02P1/08
Filed: 1978-09-29
Abstract: PURPOSE: To obtain zero advance, advance, and maximum advance characteristics electrically to meed an advance characteristic required for engine.  
     CONSTITUTION: Ignition timing is automatically advanced by advancing the electrification starting time of the thyristor 12 by the output voltage of the signal generator 13, increasing with the rise of the revolving number of engine, and by supplying  the charge of the condenser 11 to the thyristor 6 through the thyristor 12 for electrification. When the revolving number of engine reaches a value or more, the  output voltage of the signal generator 13 causes electrification in the thyristor 6  before the generation of the output voltage of the signal generator 9. Thus, a fixed  advancing angle or maximum advancing angle can be obtained without causing  no further advance.

Title: Soft discrimination decoding system
Inventor: SUZUKI KUNIYUKI
IPC: H03M13/23
Filed: 1995-05-19
Abstract: PURPOSE: To enhance error correction capability by calculating a standard reference from a reception level of a reception signal based on a signal set command and normalizing the reception level so as to calculate level reliability information thereby reducing fluctuation width of the level reliability information. CONSTITUTION: A standard reference value is calculated from a reception level signal from a reception level detection section 14 based on a signal set command being an output of a signal set detection section 12. The standard reference value in response to each error correction system is generated by a standard reference value generating section 20. The standard reference value is set to each signal set and the result obtained by normalizing the reception level by the standard reference value is used for level reliability information. That is, since the level reliability information is normalized by the standard reference value for each signal set, a soft discrimination threshold level covering not fluctuation in the reception level over entire time in real environment but fluctuation of a reception level in a signal set may be used.  Thus, a required bit number for the soft discrimination threshold level is reduced and then the circuit configuration is simplified.
